Insights
Household incense burning is linked to delayed gross motor development in children. This study highlights potential risks of indoor air pollution from incense on neurodevelopment milestones.
Area of Science:
- Environmental Health
- Pediatric Neurodevelopment
- Epidemiology
Background:
- Biomass burning is a known air pollutant linked to neurodevelopmental issues.
- Limited research has explored the impact of indoor biomass burning, such as incense, on child development.
- Previous studies on incense burning in Taiwan primarily focused on birth weight and allergies.
Purpose of the Study:
- To investigate the association between household incense burning exposure and neurodevelopment in children.
- To provide insights into the potential risks of common household rituals on early childhood development.
Main Methods:
- Utilized data from the Taiwan Birth Cohort Study (TBCS), a nationwide representative cohort.
- Collected data via home interviews and structured questionnaires at six and eighteen months of age.
- Employed multivariate logistic and Cox proportional hazard regression analyses to assess the relationship between incense burning and neurodevelopmental milestones, controlling for confounding factors.
Main Results:
- Analysis included 15,310 term singletons.
- Household incense burning was significantly associated with delays in gross motor neurodevelopment milestones, including walking with support and walking steadily.
- Both occasional and persistent incense burning showed increased odds and hazard ratios for delayed gross motor development.
Conclusions:
- Household incense burning exposure is associated with delayed gross motor neurodevelopmental milestones in children.
- Further research is needed to understand the underlying mechanisms and establish a causal relationship.
- Findings suggest a need for awareness regarding indoor air quality and its impact on child neurodevelopment.
Background:
Air pollution from biomass burning were associated with neurodevelopmental deceleration, but limited studies concerned about the effect of indoor biomass burning. Incense burning is a common household ritual practice in Taiwan, while past studies mainly focused on birth weight and allergic disease.
Objectives:
We aimed to find the association between incense burning exposure and children's neurodevelopment.
Methods:
In Taiwan Birth Cohort Study (TBCS), a nationwide representative birth cohort study, children were assessed upon home interview with structured questionnaires upon six and eighteen months old. Multivariate logistic and Cox proportional hazard regression adjusting confounding factors were applied to explore the odds ratio (OR) and hazard ratio (HR) between household incense burning exposure and caregiver-reported neurodevelopment milestones.
Results:
In this study, 15,310 term singletons were included, and household incense burning was associated with delay in gross motor neurodevelopment milestone, such as walking with support (Occasional incense burning: OR = 1.26, 95% confidence interval (CI): 1.08 to 1.47, HR = 1.07, 95% CI: 1.03 to 1.11; persistent incense burning: OR = 1.44, 95% CI: 1.22 to 1.69, HR = 1.11, 95% CI: 1.07 to 1.16) and walking steadily (Occasional incense burning: OR = 1.14, 95% CI: 0.98 to 1.32, HR = 1.07, 95% CI: 1.03 to 1.11, persistent incense burning: OR = 1.24, 95% CI: 1.06 to 1.45, HR = 1.09, 95% CI: 1.04 to 1.13).
Conclusions:
Our study suggested household incense burning exposure was associated with delay in gross motor neurodevelopmental milestones. Further research is warranted to elucidate the possible mechanism and causal relationship.
